My "game I'd love to see" is something along the same lines as the PC games "Masters of Magic" or "Age of Wonders", where it's different players, each playing their own race, conquering cities, using those cities to produce more troops, all the while casting spells to beef them up or change the entire landscape.
Seeing "Small World" on the horizon for Days of Wonder got me thinking along these lines; that I'd love to see a game that's less abstract. Ideally I'd love to see the ability for players to research new spells for their arsenal, as well as a system similar to Titan where battles take place on a tactical level on a separate board.
Tall order, but I think FFG has some talented people working for them.
